SUPPORT FOR OXY-ACETYIJENE "JJORCH'E'IS.

Application filed June-19, i924, Serial N0.- 721,009:

To all "whom it may concern:

Belt knownthat we, J 01m llfs'rnvniws and NELSON CORY, citizens of the United I the provision of a strong durable frame of simple construction whereby an o'xy-acetylene torch may supported adjacent the work and guided so that the cutting flaine from the torch will be caused to follow a w path corresponding to the contour of the material to be cut.

panying drawings, and the invention resides in certain novel features which willloe par ticularly pointed out in the appended claims In the drawings Figure 1 is a side elevation of ourv improved device showing a railroad track rail in section and supportedtherein Fig. 2 is a. plan View of the "device, and

Fig. 3 is a detail perspective view of the guide plate.

In carrying out our invention, we employ a base plate 1 having reinforcing ribs formed 011 its under side and constructed with a central slot 3 in which a cam lever 1 is mounted. The base plate is also constructed at one side with an overhanging flange or lip 5 which is disposed in divergent relation to the surface of the base plate, as shown most clearly in Fig. 1, whereby one base flange 6 of a track rail may be engaged under the said lip and held by the same and the base plate. The head 7 of the cam lever 4. is adapted to bear against the base flange of the track rail opposite the li 5 and when it is turned home force the rail firmly'against the bight presented by the said lip and the base plate so that the rail will be securely held while it is being acted upon by the torch. The reinforcing ribs 2 are provided Another object. of the invention is to provide a construction whcreby the guiding member may be changed at with aplurality of openings 8 therethrough and the camlever is likewise providedwith a plurality of openings 9 so that the full crum bolt 10 may be engaged through the proper openings to set the cam lever for any particular work.

The ribs 2 merge into a standard 11 which extends outwardly and upwardly from the base plate and the lip 5 and constitutes the main support for the carrier 12 in which the torch is secured. By reference to Fig. 2, it willbe noted that'the carrier 12 is disposed so that the sleeve or barrel 13 inwhich the end of the torch will be held isadjacent but beyond the side-edge oft-he base plate and, consequently, the flame from the torch may be directed upon and over the entire extent of the work without playing-upon-the base plate as the torchis manipulated. The carrier consists of a bar at one end ofwhich the sleeve 13 is formed and which is pro vided with longitudinal slots 14- in which are fitted bolts 15 carrying rollers 16 which play in the slots 17 and 18 of the guide plate 19.

The guide plate is secured rigidly upon the standard 11' parallel with the same and in spaced relation thereto by shouldered bolts 20 -having their threaded extremities inserted through the standard and through the upper. and lowerends of the guide plate, respectively, as clearly shown, so that, when nuts] fitted on. the extremities of the said bolts are turned home,the guide plate and the standard will be firmly-secured together and held-in the spaced relation. The bolts 15 which" are inserted through the slots 14 of the carrier 12 are engaged through a handle or lever 21 disposed between the guide plate and the standard 11 and close to the guide plate so that the carrier and the handle will be held adjacent the guide plate and will be thereby prevented from having lateral movement. The forward bolt 15 passes through and plays in the slot 18 in the guide plate which extends rearwardly or outwardly and slightly upwardly with respect to the work while the outer bolt 15 plays through the cam slot 17 which is of a general arcuate form concentric with the front end of the slot 18 and has offset portions 22 adjacent its ends.

It is thought to be evident from the fore going description, taken in connection with the accompanying drawings, that, as the handle or lever 21 is swung upwardly or downwardly, the inner or front bolt 15 will Lit) serve as a pivot about which the vertical movement may occur. At the same time the handle may be given an eccentric or irregular movement which will cause the sleeve 13 to advance or recede relative to the work as well as swing vertically relative thereto, and this eccentric movement will be accelerated and emphasized by the engagement of a roller 16 with the oflsets 22 of the guide slots 17. The longitudinal slots 14 in the carrier permit the same to be adjusted endwise with respect to the handle so that the head 13 may be set at a greater or less distance beyond the inner edge of the guide plate according to the dimensions 01' the rail or other part which is to be operated upon. The guide plate may have the slot 17 of any desired form so that the movement of the torch will follow the outline of the work, and it is the intention to supply guide plates in various forms so that they may be used in.- terchangeably as circumstances may demand.

Having thus described the invention, we claim:

1. A device for the purpose set forth comprising a base plate, means for clamping work thereto, a guide plate secured rigidly upon the base plate, a carrier disposed at one side of the guide plate and parallel therewith, a handle disposed at the opposite side of the guide plate and parallel therewith, and means for rigidly connecting the handle and the carrier, said means being operatively engaged with and extending through the guide plate whereby to impart to the carrier movement along a line corresponding to the contour of the work.

2. A device for the purpose set forth comprising a base plate, means for clamping work to the base plate, a standard on the base plate at one side thereof, a guide plate secured rigidly to the standard in spaced relation thereto and adjacent an edge of the base plate, said guide plate being provided approximately midway its height with a slot extendin in a direction toward and from the work and further provided with an arcuate cam slot extending in the general direction of its height, said arcuate slot being described about a center located in the first-mentioned slot, a carrier arranged adjacent one side of the guide plate, a handle arranged adjacent the opposite side of the guide plate, and connections between the carrier and the handle playing in the slots in the guide plate whereby the carrier may be caused to move over a path corresponding to the contour of the work.

A device -for the purpose set forth comprising a base plate, means for clamping work to the base plate, a standard on the base plate at one side of the work, a guide plate secured rigidly to the standard in spaced relation thereto, said guide plate being provided substantially midway its height with a slot extending in a general horizontal direction toward and from the work and being further provided with an arcuate cam slot extending in the general direction of its height, said arcuate slot being described about a center located in the first-mentioned slot, a carrier arranged adjacent one side of the guide plate and provided with alined longitudinal slots, a handle arranged adjacent the opposite side of the guide plate, and connecting bolts secured in the handle member and engaged in the longitudinal slots of the carrier and extending through and playing in the respective slots in the guide plate whereby the carrier may be caused to move over a path corresponding to the contour of the work.

In testimony whereof we aifix our signatures.

NELSON CORY.
